You to Pilotchute have hit the nail on the head. It is not an industry for the faint hearted. You have to put it first and everything else second. Expect a few tears before bedtime, and a few regrets.
Some get lucky, network well, have rich parents, Mensa IQ (RAAF candidates) or simply are single minded.
If you make it you will look back and smile, if you don't you may become bitter and twisted and post lots of crap on this site, or you may just move on.
Aviation and Aviators are not "special", most industries follow a similar template.
